I couldn’t find a good answer I’m searching as most posts understandable care more about upgrading from Silver to Gold.

Can anyone tell me how long it takes to upgrade from Jade to Silver after a qualifying SP earn pushes you past 450 SP in the preceding 365 days?

We aren’t so interested in the benefits but more a case of caring about upcoming flights and whether those SP will go towards the maintenance of Silver or be “wasted” during the Tier upgrade process.
